Thermal map of flow field...

Thermal map over the Episode 61g lava flow. Cooler colors (blue and green) show cooled, inactive portions of the flow surface. Hot colors (red and orange) show areas of active surface breakouts. Areas of the Episode 61g flow not covered by the thermal map - because of clouds, rain, or incomplete image coverage - are shown as dark gray.

The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field.
